Magnetic-angle sensors deliver 0-360° measurements with thermal stability
LF53466 and LF53464 tunneling magnetoresistance (TMR)-based, magnetic-angle, omnipolar sensors provide 0° to 360° angular measurements in harsh environments with minimal thermal drift.
Both sensors employ TMR in a dual, push-pull, Wheatstone bridge configuration, each featuring four high-sensitivity sensing elements, which enable accurate angle detection along the X and Y axes. These sensors are an alternative to Hall-effect devices by providing thermal stability, supply voltage compatibility, and enhanced measurement precision.
LF53466 is housed in a standard TSSOP8 package, and offers precision angle sensing with an error of less than 0.8° in the 200-800 Gs magnetic-field range.
LF53464 is available in a compact LGA8L package, and achieves even greater accuracy, with an angle error below 0.6°, while enabling wider airgap capability and compatibility with smaller, lower-cost magnets.
